    Hi,

    After some input on what to put in my laptop.

    Looking at either Raid 0 on 2 x 7200rpm drives or going for an SSD.

    Yes it is a 17" laptop and supports raid 0 and 2 drives.

    Basically for a workstation using Visual Studio, SQLServer etcetc

    Thoughts?

    Thanks in advance.

    a single SSD or a single harddrive will be better than two.
    Why,
    Well you see those hdtune benchmarks and how the performance is near double with 2 drives. Well hdtune is a synthetic benchmark, which only shows performance which we users will never be able to see.
    Unless you are buying a D900K, you do not have a hardware based raid controller. That means that the raid controller your system has, has a software based raid controller. SOftware raid is about 7% efficient at best, usually lower than that, around 5%. Hardware raid is much more efficient, around 85% efficient. This is because their is a physical chip separating the data files, and not the shared system serial bus.
    So in essence buying that second harddrive will give you about a 5% performance increase in harddrive speed, which will be unnoticeable. The same will happen with SSD's as with mechanical drives.
    You will only benefit from Raid 1, by having a backup copy of everything. Other than that Raid 0 is a complete waste of time, cause of the software raid controller.

    Go for one of the latest generation 7200rpm drives from Hitachi, Seagate, Fujitsu or WD. They all perform phenomenally well for laptop drives.
    For SSD's, well I am no ssd expert, their is a guide by our SSD master LES.
    I find SSD's to be a complete waste of money right now, since they are so expensive. the ones which are cheap tend not to work, so watchout.
